He represented three days following discharge with sudden onset breathlessness and chest pain. Initial imaging suggested the presence of a left pneumothorax. Following further clinical decline a plan was made to insert a CT guided chest drain. However, imaging in the prone position for the procedure unexpectedly revealed a large left lower lobe pneumatocele with only a very small pneumothorax. Events and appearances suggest that this is a rare case of delayed COVID-19 pneumonitis-related pneumatocele formation.
